So, in the beginning, when I heard of this drama, it sounded all pointless. K-dramas mostly don't have such sci-fic topics. Hence, I had little to no expectations for this. I decided to watch it for time pass. But, it actually exceeded my expectations! The story is pretty loyal to the web novel and gives a cartoonish vibe. The actors could not have been better! The acting is absolutely great. Somethings could have been explained a little better, for example the ending scene could have been extended to just before Min-ah enters the machine and then Mr.Ko could stop her there. Overall, it was a light and good watch. It has the perfect dry humour! Episodes are small but will keep you hooked for sure! It's great to see the change of genre once in a while in a K-drama. Also, this thing needs to be understood that Min-ah played by Kim Yoo Jung is not necessarily the main character just because it is played by a famous actress. The two MLs should definitely get more focus as they are the one's taking the drama. Many people would get into this because of Kim Yoo Jung (I did too) but then complain that she didn't get enough screentime. Do understand that her role was to be converted into a chicken nugget and so it's just appropriate that she doesn't have much screen time. The acting of the two MLs is worth the praise. It's a good watch for sure!!
